I live in SF, and I take it daily. It's cheaper than paying for the parking garage near the office. And it's cheaper than Uber: the base rate is similar to Uber's, but there is no need to add a tip.
Waymo sometimes does weird, unexpected things - but safely. Once it seemed to change its mind about the optimal route a few times over the course of 10 seconds, switching safely between two lanes back and forth a few times before committing. It used its turn signal fine, and the lanes were clear, so it wasn't a problem, but this isn't something humans do.
Sometimes it behaves oddly, but I have developed confidence that it will do those odd things safely.
